I’m afraid I don’t Zwift so I don’t know (I am in IT thought, and I know it’s a lot harder to do stuff on Android than iOS because of all the different hardware options that are out there), particularly around the graphics chipsets.

The Fire tablets are not the fastest around (hence why they are fairly cheap).

The brand is Ergotron - they seem to sell a lot of wall mounts of various types. I couldn’t find an exact match on their website to link you to though. Truthfully, the wall mount came with the house. I just moved it to the basement from a bedroom so I could use it for training. It looks like similar stuff retails around $200. It is useful as a set up.

This is my cave. Watch the 2 hour live or recorded podcasts on my iPad , big speaker under the fan in front. Have the TR workout on my plugged in iPhone (on the lower level of my tripod with food there too.) controlling the Tack Neo in Erg mode. Currently in SSB II Hi Vol . I’m facing the windows in my garage double door so I can look outside and watch it snow!
